Microdata doesn't go out of its way to be compatible with existing RDF  
vocabularies, in fact I'd argue that the RDF extraction algorithm creates  
some pretty ugly URIs that anyone who actually likes RDF would frown upon  
and not want to use. In any event there's very little "RDFness" over the  
syntax itself, the model is key-values, not triples.

This isn't a difference between microformats and microdata. The microdata  
vocabulary *had* the 'n' optimization, but it was removed after I showed  
that it didn't work for e.g. Chinese or Vietnamese. I tried to learn from  
this community why it isn't a bad idea, but there wasn't much useful  
feedback. It really should be removed from microformats too, but that's  
probably too late.
